post ni sir traxxx "How to do it: ( to know where is the Pilot Air screw, see chapter 3:11 of the T135 service manual)
- warm up your engine
- after warm up, turn off
- turn the PILOT AIR SCREW clockwise to until its fully close (this is called IN, because the screw is going IN)
- now mark the point where it was fully closed (that will be your mark to know if you 360 degrees or 1 turn)
- now adjust it to 2 and 1/4 turns counter clockwise (this is called out because you are making the screw going OUT)" hmmm
